—Hаving been found guilty by a jury, defendant appeals from a judgment of conviction of murder in the first degree (Pen. Code, §187) with a penalty of life imprisonment.
On Sunday, July 19, 1964, Virginia Mae Cothern was working as a barmaid at the Sidewinder Bar in El Monte. When Fred Baker, the owner of the Sidewinder, left at 7:30 p.m., several customers were drinking at the bar. He told Miss Cothern to close at about 10, the normal Sunday closing time. At approximately 9 p.m., Richard Lopeman and five others arrived at the Sidewinder.
Appellant and Miss Cothern were the only ones present when Lopeman and his group arrived. The newcomers went to the back dining area and began to sing and drink beer. A while later Miss Cothern brought appellant over and introduced him to Lopeman and his cronies. Appellant joined in the singing and conversation. Since no other customers were at the bar, Miss Cothern spent most of her time with the singers. On one occasion she sat on appellant’s lap and appellant put his arm around her waist. Appellant seemed to have had less to drink than the others. At 10 o’clock, Miss Cothern announced that it was closing time. Lopeman and his friends departed. On his way out, Lopeman talked briefly with appellant. Thereafter appellant and Miss Cothern were left alone in the bar.
When Baker arrived at the Sidewinder the next morning, Mary Kern, Miss Cothern’s roommate, was waiting outside. Baker noticed that the outside light and window lights were still on. Entering the bar, he saw that the place was not cleaned up and that the back door was not closed. In the dining area, he found Miss Cothern’s nude body lying in a considerable amount of blood. The cash register was empty, and some loose change was scattered on the floor. Baker estimated that $115 to $120 was missing.
After the police arrived, it was noticed that there were footprints in the fluids surrounding the body and on the body itself. The causes of death were strangulation and a stab *601 wound in the neck, which caused profuse hemorrhage. There was evidence of sexual molestation. A pair of sunglasses, an empty Marlboro cigarette pack and a broken ball point pen were found near the body.
Lopeman, upon hearing of thе homicide, offered to help the police. As he was an accomplished artist, he prepared a sketch of the last person in the Sidewinder on July 19. The sketch showed a person wearing a goatee. On five occasions Lopeman went to the police station to look at suspects. None was appellant.
Police Sergeant Wrona led the investigation. He published Lopeman’s sketch of the suspect, and as a result numerous leads were received. A few days after the crime, apрellant’s aunt called and told Sergeant Wrona the published sketch resembled her nephew. Sergeant Wrona did nothing about this call; he was busy with other leads. The officers investigated at least one hundred suspects. On Friday, August 28, Sergeant Wrona finally called appellant and asked him to come to the station to talk about what occurred at the Sidewinder on July 19. Appellant said he knew what the sergeant was referring to, and said he would come right down.
When appellant first arrived at the station, Sergeant Wrona asked for apрellant’s name and address and got a physical description. He observed that appellant did not have a goatee. Lopeman was summoned to the station; he signalled covertly to Sergeant Wrona indicating that appellant was the man Wrona had been searching for. Appellant had already admitted that he had been singing with a group of men at the Sidewinder on July 19. Appellant said he heard about the murder the next day.
Sergeant Wrona then invited appellant into the kitchen for a cup of coffee аnd asked him to relate what happened on July 19, 1964. Appellant stated that he went to the Sidewinder at 7 p.m. on July 19. Other customers were present at this time; one drunk had an argument with Miss Cothern over an alleged shortchanging. Later appellant was invited to sit with a group singing in the back dining area. On one occasion the victim sat on his lap. When the victim announced that it was closing time, the others left and appellant was alone with her. He noticed that he had lost his sunglasses, a pen or pencil, and a Marlboro pack. When the victim went into the dining area, he left. He went for a long walk in the area, returned home and went to bed.
Later in the day Sergeant Wrona and the appellant, aceom *602 panied by Sergeant Human, went to an interview room, where appellant related the same story to Sergeant Human that he had previously told Sergeant Wrona, adding that he owned a 1956 Ford. At this time he was not under arrest. • At the officer’s request, appellant showed them both his shoes. The officers immediately saw that the pattern on the soles resembled the prints found in the fluids near the body. Laboratory examination later revealed that appellant’s shoes probably did make the footprints near the body.
The officers then asked him to “tell us just what happened at the Sidewinder Cafe on Sunday night.” Appellant replied that when he heard the next day that Virginia Cothern had been choked he realized that he had strangled her. While she was counting the money, he had gone behind the bar and grabbed for her neck. In an ensuing violent struggle her clothes had been torn off. After stabbing and choking her, he wrapped some clothing around her, took the money and left. At home he noticed some debris on his pants; he removed them, left his home and, walking past a lot where some cars were parked, placed the pants in a Buick or Oldsmobile. He purchased a Ford convertible with the money he had taken. It was not until this point that appellant was informed of his right to an attorney and to make a telephone call, and placed under arrest. Sergeant Wrona testified that all the statements were made voluntarily but that once Lopeman identified appellant as being the last person in the Sidewinder on Sunday night, he (Sergeant Wrona) would not have let appellant leave the station without first obtaining his account of what occurred.
All of Sergeant Wrona’s testimony regarding the content of appellant’s statement, and the circumstances in which it was given, was heard by the judge out of the presence of the jury. The judge concluded that the investigation focused on appellant as a prime suspect when the officers saw that appellant’s shoes appeared to be the ones that had made the prints at the scene of the crime. Therefore, under
People
v.
Dorado
(1965)
*603
Appellant’s first contention is that the prosecutor cоmmented on appellant’s failure to testify and that a reversal is therefore required under
Griffin
v.
California
(1965)
Although many convictions have been reversed for impermissible comment, none has specifically defined what
Griffin
comment is. For example, in
People
v.
Odom
(1965)
In
People
v.
Beghtel
(1966)
tended
Griffin
error.
Griffin,
said the court, did not require the prosecutor to abstain from stating that testimony is uneontradicted. A prosecutor’s comment that testimony describing criminal conduct of a defendant is uncontroverted, is not, itself, a comment on defendant’s failure to testify. In
People
v.
Modesto
(1967)
“Although the comment now before us leaves more to the jury’s imagination than did the remarks which the Griffin court held unconstitutional, we cannot ignore the transparent implications of the words chosen by counsel for the prosecution in the instant ease. The rulings of the courts should not be so esoteric that а judgment must turn on the superficial difference between this prosecutor’s phraseology and that found improper in Griffin.” (66 Cal.2d at p. 711 .)
Here the defense had rested without presenting any evidence. The prosecutor pointed out many times in the course of a lengthy argument that various points made in the People’s case had gone without contradiction. The total purport of these observations is fairly summarized in the following quotation from the argument:
“Again, we have the situation where the State has presented very persuasive evidеnce that the defendant did murder her, as I have repeatedly described that he did, and there is no challenge, no testimony whatsoever to refute that. ’ ’
These comments were proper; they “relate to the state of the evidence before the jury and not to defendant’s failure to take the stand and testify.”
(People
v.
Montigo, supra,
*605 “Of the several voices that we could hear in this case, one voice has been forever stilled. We will not hear from her.” The other voice, of course, was that of appellant who, according to the prosecution’s theory, was the only other person present at the time of the murder. Then, in reference to the portion of appellant’s admission to Sergeant Wrona which had been received in evidence, the prosecutor stated: “The defendant, in his own words spoken to Sergeant Wrona, there is no denial of those words, with the defendant present, . . .” (Italics added.) Similarly, in another passage, the prosecutor said: “Now, as far as how the bottle was broken . . . there would be two people, possibly, who could answer that, and one of them, of course, is dead.” These comments are similar to the comment held to be objectionable in People v. Modesto, supra,66 Cal.2d 695 , 711: “Who is the only person around who had blood on him, besides the two little girls? You know who he is. He is sitting here in this courtroom—and just sitting.” We cannot say here, as did thе Court of Appeal in People v. Montigo, supra,248 Cal.App.2d 32 , 38: “It is true the jury might well have concluded that by failing to take the stand and explain these peculiar circumstances defendant opened the way for an inference of guilt. The inference, however, would be that of the jury, not one argued to them by the prosecuting attorney. ...”

error does not require reversal of a judgment if the court is 1 ‘ able to declare a belief that it was harmless beyond a reasonable doubt.”

California
(1967)
Appellant complains of the giving of an instruction based upon form instruction number 51 in the work, California Jury Instructions, Criminal. The form has been obsolete and erroneous since
Griffin. (People
v.
Davenport
(1966)
Appellant’s next contention is that, under
People
v.
Dorado, supra,
We find in the cases no clear-cut test for determining when an investigation has ceased being a general inquiry into an unsolved crime and has begun to focus on defendant. Appellant, relying on
People
v.
Chaney
(1965)
Ill the present ease Officer Wrona had checked more than 30 suspects in a little over a month. He was primarily interested in locating the person who resembled Lopeman’s sketch. In looking through his records, he realized he had not followed up the cаll from appellant’s aunt. He called appellant and invited him to the station. The investigation thus had not focused on appellant when he replied over the telephone that he knew of the murder. When appellant first arrived at the police station he admitted being at the Sidewinder on July 19. Many others had also been there and there was still no cause to focus suspicion on -appellant. When Lopeman identified appellant as the last person known to have been in the Sidewinder other than the victim, it did nоt mean that appellant necessarily committed the crime; but it did establish in the officer’s mind appellant’s identity as the prime suspect he had been searching for so laboriously. The investigation focused on appellant at that moment. Thus, in our view, the *608 facts do not support the conclusion of the trial judge that the investigation had not focused and that Sergeant Wrona was continuing his general investigation of an unsolved crime.
We cannot say, however, that the second
Dorado
element (custody) came into play as a matter of law at that point. Sergeant Wrona аsked appellant to have a cup of coffee and tell him what happened. It is not necessary for a person to be under arrest for him to be in custody. Even one who comes to a police station voluntarily may be regarded as in custody.
(People
v.
Arnold
(1967)
Sergeant Wrona and Sergeant Human then took appellant to an interrogation room in the police station. Thereafter, when appellant had been at the police station about two hours, the examination of appellant’s shoes took place. The trial judge concluded that the investigation had not focused upon appellant so as to bring Dorado into play until the shoes were identified. We have аlready indicated why the evidence compels the conclusion that focus occurred earlier, when Lopeman identified appellant. We consider it highly likely that the second Dorado element, custody, came into play when the amenities of coffee drinking and preliminary conversation ended and appellant was taken by the two officers to the interrogation room; appellant must by then have believed, “as a reasonable person” that his freedom of action was restricted, as in Arnold.
*609
To determine if thе’ police áre carrying out a process of interrogations that lends itself to eliciting incriminating statements, so as - to fulfil the third
Dorado
prerequisite, the court must analyze such factors as the length of the interrogation, place and time of the interrogation, the nature of the questions, the conduct of the police and all other relevant circumstances.
(People
v.
Stewart
(1965)
There was substantial conflict in the evidence, and in the inferences to be drawn therefrom, as to the situation which prevailed before appellant was taken to the interrogation room. It was the responsibility of the trial judge to resolve such conflicts and uncertainties and he did so after an elaborate hearing conducted out of the presence of the jury. His determination finds reasonable support in the evidenсe; therefore, it is not to be disturbed upon appeal. (Cf.
People
v.
Wood
(1967)
Appellant contends that the court erred in receiving in evidence a pair of blood-stained pants which were discovered as a result of information which came to police as part of appellant’s inadmissible confession. The defense did not bring the point to the trial court’s attention by appropriate objection when the evidence was offered; nevertheless the
*610
court did, upon a later motion strike, and admonish the jury to disregard, all evidence having to do with the pants. At the same time the court directed the prosecutor not to refer to the stricken evidence in his closing argument. The court thus correctly anticipated the holding of the California Supreme Court, in
People
v.
Buchanan
(1966)
In his opening statement the prosecutor referred to appellant’s purchase of the car one day after the murder, appellant’s statements made to the officers, and appellant’s blood-encrusted pants. It is now contended that these comments constituted error because the pants, statements and reference to the car were inadmissible. The pants and part of the statements were excluded by the court, but evidencе concerning the purchase of the car was received without appropriate objection. There is no indication that the prosecutor was guilty of bad faith in mentioning matters which later were excluded by the court. Generally comment in an opening statement on evidence which is later ruled inadmissible is not reversible error.
(People
v.
Hurst
(1957)
Finally, appellant contends that the prosecutor committed error by giving his personal opinion of appellant’s guilt. In his closing argument the prosecutor stated: “But I do ask you to find it to be of great signficanee that the People have presented
what I regard as such a conclusive case
in every respect and the defense has chosen to not present any evidence in contradiction.’’ (Italics added.) California cases
*611
have held that a prosecutor’s statement, not based on legitimate inferences from the evidence, that he has personal knowledge of defendant’s guilt or that he would not prosecute unless defendant was guilty, is misconduct.
People
v.
Modesto, supra,
The judgment is affirmed; the appeal from the order denying motion for new trial is dismissed.
Devine, P. J., and Rattigan, J., concurred.
Appellant’s petition for a hearing by the Supreme Court was denied May 29, 1968. Peters, J., was of the opinion that the petition should be granted.
